Evolutionary Applications, Volume 19, Issue 4, April 2026.ABSTRACT By modifying biotic and abiotic environments, urbanisation can influence the evolutionary adaptation of organisms, especially when their distribution is fragmented. However, the effects of urbanisation on evolutionary adaptation remain poorly understood within a metapopulation framework, where high gene flow and recurrent extinctions ...

BMC Plant Biology, 2010 Background Impatiens (Impatiens walleriana) is a top selling floriculture crop. The potential for genetic transformation of Impatiens to introduce novel flower colors or virus resistance has been limited by its general recalcitrance to tissue culture and

INDEPENDENT ORIGINATION OF FLORAL ZYGOMORPHY, A PREDICTED ADAPTIVE RESPONSE TO POLLINATORS: DEVELOPMENTAL AND GENETIC MECHANISMS [PDF]
, 2016 Observations of floral development indicate that floral organ initiation in pentapetalous flowers more commonly results in a medially positioned abaxial petal (MAB) than in a medially positioned adaxial petal (MAD), where the medial plane is defined by ...

Combined stress from parasites, pesticides and lack of flowers drives bee declines [PDF]
, 2015 Bees are subject to numerous pressures in the modern world. The abundance and diversity of flowers has declined, bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by ...

Spatial Mismatches of Plant‐Pollinator Interactions Under Future Climate Conditions
Journal of Biogeography, Volume 53, Issue 4, April 2026.ABSTRACT Aim Global change could disrupt critical ecological interactions, especially if interacting species shift their geographic ranges at different rates or in different directions. Functional redundancy within generalized networks could make them more resilient to climate change than networks with highly specialized interactions.

Photoreceptor spectral sensitivity in the bumblebee, Bombus impatiens (Hymenoptera: Apidae).
PLoS ONE, 2010 The bumblebee Bombus impatiens is increasingly used as a model in comparative studies of colour vision, or in behavioural studies relying on perceptual discrimination of colour.

Observations on Colony Size in Bumblebees (\u3ci\u3eBombus\u3c/i\u3e Spp.) [PDF]
, 2017 (excerpt) One factor to consider when attempting to rear bumblebees (Bombus spp.) for pollination of crops is potential colony size. Species which emerge from hibernation early and continue to produce workers late in the summer or early fall are likely ...

Longevity in plants impacts phylogenetic and population dynamics
New Phytologist, Volume 250, Issue 1, Page 661-671, April 2026.Summary Phylogenies of long‐lived plants often exhibit short molecular branch lengths and high levels of gene‐tree conflict. However, the biological mechanisms underlying these patterns remain unclear. We examine this with simulations and through empirical examination of several large seed plant clades.
